Blind actuator 4-way DC 24 V with manual operation for KNX REG plus blind actuators with integrated bus connection, manual operation and status display for each output. For controlling electrically operated blinds, roller shutters, awnings, ventilation flaps or similar blinds. Features: Blind position can be controlled directly. Slat position can be controlled directly. Behavior in the event of bus voltage failure and return can be set. Travel times can be parameterized separately with travel time extension for travel to the upper end position. Central control of all blind outputs possible. Feedback of the blind position or the slat position. Feedback can be delayed after bus voltage return. Assignments to up to five different safety functions (three wind alarms, one rain alarm, one frost alarm), optionally with cyclical monitoring. Forced position function can be implemented for each blind output. Inclusion in scenes possible, max. eight internal scenes per channel can be parameterized. Storage function for light scenes. Sun protection function can be activated with fixed and variable blind or slat positions. Extended sun protection with extensive control functions. Integration into the building's temperature management possible. Blocking of individual outputs manually or by bus. Active or passive (object can be read out) cyclical feedback functions. Construction site operation: Outputs can be operated manually without bus voltage, only with the operating voltage. For low voltage DC 12 to 48 V. Independent control of the four blind outputs. Notes: Installation on DIN rail.
